I have a 2000 ford focus. The check engine light is on again after mechanic fixed the mass air flow sensor now the light is on again, what do I need to do to fix the problem?
Then probably the check engine light is because of something else, and could be a number of things. Heck it could even be a badly screwed gas cap, since it keeps the tank air tight and newer cars like yours test what they call the EVAP system and will turn on the check engine light if it finds even a very small leak. On my car right now i have a check engine on because the filler neck is rusted and so the gas cap doesn't seal correctly just so you know how far this can go. So if you really want to get the light off, you will need to have to codes pulled out of the computer to see what the problem is this time and fix it. Sorry if this isn't exactly a precise answer, but the check engine light is only there to let you know there is something out of wack, be it big or small, important or not, and there are close to about 1000 different codes that can be given by the computer that will light up the check engine, so without any codes, all we can do is poke in the dark until we find the target, so you will definetly need to get a scanner plugged in the OBD plug to get the codes out and find out what's wrong. That doesnt mean you HAVE to get it fixed on the spot though, most garages will charge a small fee just to get the codes out and give them to you if you want to fix it yourself. So just go to a garage you trust, or a good friend which also happens to be a mechanic with a scanner and have the codes checked. After that, feel free to write me up and i'll help you fix the problem. Hope this helps :)
